Anomalous Orbital Structure in Two-Dimensional Materials
Researchers explored how structural distortions of the atomic lattice influence exotic electronic states in two-dimensional transition-metal dichalcogenides (TMDs). Polarization-dependent spectroscopy revealed an unexpectedly large crystal-field splitting of the valence electron states, a result of strong hybridization in metal–chalcogen orbitals. Read more »
Multimodal Study of Ion-Conducting Membranes
Using multiple x-ray characterization tools, researchers showed how chemical and structural changes improve the performance of a novel ion-conducting polymer (ionomer) membrane from 3M Company. The work provides insight into factors impacting the proton conductivity of ionomers used for fuel cells and the production of hydrogen fuel. Read more »
Infrared Nanospectroscopy at Graphene–Liquid Interfaces
Researchers developed a new infrared approach to probing the first few molecular layers of a liquid in contact with a graphene electrode under operating conditions. The work offers a new way to study the interfaces that are key to understanding batteries, corrosion, and other bio- and electrochemical phenomena. Read more »

Controlling Spin in Antiferromagnetic Nanostructures
Researchers discovered that the spin configuration of a nanostructured antiferromagnetic material can be affected by the dimensions of features imprinted onto the material. The results suggest that nanoscale patterning can be a viable tool for engineering spin configurations in future antiferromagnetic spintronic devices. Read more »
Multiple Levels of Chirality from Achiral Molecules
Liquid crystal samples were found to exhibit up to four levels of chirality, despite being made up of achiral molecules. The work sheds light on how molecular properties and competing interactions “propagate” order from the molecular level up to the microscale, leading to complexity similar to that found in biological materials.

A Citizen-Science Computer Game for Protein Design
Using the computer game, “Foldit,” nonexpert citizen scientists designed new proteins whose structures, verified at the ALS, were equivalent in quality to and more structurally diverse than computer-generated designs. The work shows the potential of using crowd-based creativity in the design of new proteins for fighting illness and disease. Read more »
